如何在Android上的React Native中包含和读取源映射文件

project.ext.react = [
    entryFile: "index.js",
    bundleAssetName: "index.android.bundle",
    bundleInDebug: true, // 设置为true以在调试模式下包含源映射文件
    devDisabledInDebug: false, // 设置为false以在调试模式下启用开发者菜单
]

// 添加以下代码
def enableSeparateBuildPerCPUArchitecture = false

def enableProguardInReleaseBuilds = true

// ...

// 添加以下代码

    devDisabledInRelease: true, // 设置为true以在发布模式下禁用开发者菜单
    enableHermes: false, // 如果使用Hermes引擎，请将其设置为true
    enableSeparateBuildPerCPUArchitecture: enableSeparateBuildPerCPUArchitecture,
    hermesCommand: "../../node_modules/hermes-engine/%OS-BIN%/hermesc", // 如果使用Hermes引擎，请根据操作系统设置正确的路径
